1. Honeycombing

Subpleural honeycombing forming several layers of cysts in a 73-year-old man with usual interstitial pneumonia.
2. Honeycombing
![honey-2](/dk/hrct/sites/default/files/2022-04/honeycoming-2%402x.jpg)
69-year-old man with usual interstitial pneumonia. Subpleural honey combing is associated with reticular pattern.
3. Honeycombing

Sagittal reformation in the same patient showing the preferential subpleural and basal distribution.
4. Honeycombing
![honey-4](/dk/hrct/sites/default/files/2022-04/honeycoming-4%402x.jpg)
56-year-old man with history of sarcoidosis. Typical honeycombing in a upper lobe distribution.
5. Honeycombing

- Coronal reformation in the same patient shows the association of honeycombing and reticulation in lung apices.
- Distribution of fibrosis to apices makes this fibrosis incompatible with UIP.
